People buy things because it provides them value. Increasing buying means that more value is being delivered to humanity. Advertising makes the world a better place.
Weird thought: if advertising is misleading harassment, perhaps it doesn't even increase consumption overall, but only consumption of the things being advertised. Perhaps people would buy more, from the market as a whole, if left in peace and given impartial advice about products only when they seek it.
I dislike this framing. Criticizing an argument is not defending, and it certainly doesn't mean the critic likes the opposing side of the argument. Seems like you're the one with the bias, having created your account just today for this one specific post.
It doesn't take a high intelligence to perceive the problem.
